Record Heat Nears Climate Thresholds

Coverage from Yale Climate Connections, ABC7 New York, and others

What's Going On

August 2026 ranked as the hottest August in multiple global datasets and tied July 2023 for the hottest month in the Copernicus record, with global temperatures about 1.

65 degrees Celsius above the preindustrial average. Human-caused warming was identified as the main driver, while a strengthening El Niño added short-term heat and could contribute to further records. Record heat affected Europe, North America and other regions through heat waves, wildfires, drought, water stress and reported deaths, although the official U.S. summer ranking remains contested because of data adjustments and measurement differences.
